The three-time Cup champion, angry over Logano blocking him on a restart with 11 laps remaining in the Auto Club 400, went up to Logano following the race. As a crew member tried to intervene, it appeared that Stewart tried to punch Logano. A shoving match ensued among the crews and Logano threw a water bottle at Stewart.

“Dumb little son-of-a-(expletive) runs us clear down to the infield,” Stewart said afterward. “He wants to (expletive) about everybody else and he's the one who drives like a little (expletive). I'm going to bust his ass.”

Logano was surprised when Stewart came up to him after the race because he didn’t even consider the move an issue.

"I had no clue what he was mad about,” Logano said. “I watched the replay. I can understand being a little irritated, but in my eyes, that’s racing. In his eyes, it isn’t.

“I’m going to have to talk to him about that. We’ve always got along really well. I’m going to see if we can work this one out.”

Logano, whose wreck with Denny Hamlin while battling for the lead resulted in a lower back compression fracture for Hamlin, was not penalized for the Stewart confrontation. He was not penalized for the incident with Hamlin—any initial penalties for that would have been done by placing him at the tail end of the lead lap rather than allowing him to keep a third-place finish.

While Logano was not penalized, he will have to deal with the consequences.

“If he ever turns down across in front of me again, I don’t care what lap it is, he won’t make it through the other end of it,” Stewart said after his 22nd-place finish.

“If I didn’t hit the chip (on my rev limiter), he wouldn’t have made it through Turn 1 to begin with. I’m tired of these guys doing that stuff, especially out of a kid that has been griping about everybody else and then he does that the next week.”

And Stewart wishes the fight could have continued.

“If NASCAR wants to let the guys have at it, it shouldn’t be any different than hockey—let us have at it and when one guy goes to the ground, it’s over,” Stewart said.
